Elaphomyces granulatus Fr. 1829
Elaphomyces granulatus is a common fungus forming large, truffle-like hypogeic fruitbodies. It is most frequently reported from Europe and Asia, but also recorded in North America, preferring acidic forest soils across a wide gradient of temperature zones from warm biomes to the boreal ones (https://globalfungi.com). It is ectomycorrhizal with spruce and pine. It is found typically in places with elevated N deposition and sufficient N availability in soils (van der Linde et al. 2018). The species was reported as arsenic hyperaccumulator (Braeuer et al. 2018).
